Apparent superluminal velocities and random walk in the velocity space
arXiv:2012.13561 · doi:10.1142/S0217732321500176
Abstract
We conjecture that the random walk and the corresponding diffusion in the relativistic velocity space is an adequate method for describing the acceleration process in relativistic jets. Considering a simple toy model, the main features of diffusion in the velocity space are demonstrated in both non-relativistic and relativistic regimes.
